Unprotected Sex

So today I went to this guys house during school in my free period and had unprotected sex. He ended up coming on my inner thigh near my vagina (a little) and the rest on his bed. I cleaned up right away but my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">EVE</a> says I have 22% of pregnancy. Is it possible?
